AI Prompt Length & Context Checker
Paste the prompt you are about to send to ChatGPT, Claude, or any other AI. This checks it for the kinds of context a rushed, typed prompt usually leaves out: specific files, real numbers, stated constraints, and an example of what you actually want.
This is a heuristic checklist that pattern-matches your text for common context signals. It is not an AI reading your prompt or judging your idea, and nothing you paste is stored or sent anywhere.
Context completeness score
What the checklist actually checks
- Enough detail. Prompts under about 40 words rarely carry enough context on their own.
- Specific files or identifiers. A path like
src/utils/parser.jsor a function name points the AI at the real thing instead of "the code". - Concrete numbers. A line number, a version, a count, a date: anything that turns a vague reference into a specific one.
- Stated constraints. Words like "must", "should", "cannot", or an explicit acceptance criterion tell the AI where the edges of the task are.
- An example. One sample input or output does more to align an AI's answer than another paragraph of description.
- More than a bare ask. "Fix my code" and "why does this fail?" are both a single guess for the AI to run with.
None of this is graded by a model. It is pattern matching against the text you paste, run entirely in your browser, and it says so on the page for exactly that reason: a heuristic score should never be mistaken for an AI's opinion of your prompt.

Does this tool use AI to grade my prompt?
No. It runs a fixed set of heuristics against the text you paste: word count, whether it names files or numbers, whether it states constraints, and whether it gives an example. It never calls a model and never judges the quality of your idea, only whether common context signals are present.
Does this tool store or send my prompt anywhere?
No. Everything runs in your browser. Nothing you paste is saved to a server, stored in your browser, or sent to any AI provider.
Why does a low score matter?
A prompt with no file paths, no constraints, and no examples forces the AI to guess, and a guessed answer is more likely to miss what you actually meant. Adding the specifics the checklist flags usually gets you a more useful first answer.
